PAPER FOLDER AND FASTER.

SPECIFICATION forming part of Letters Patent No. 656,924, dated August 28, 1900.

Application filed December 20,1899. Serial No. 740,996. (No model.)

To aZZ whom it may concern:

Be it known that L'HENRY F. BEOHMAN, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Paper Folders and Pastors; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in machinery for folding and pasting webs of paper, especially adapted for use in connection with web-printing machines, and particularly designed for use in connection with the wellknown Cox duplex web-printing machines when the same are arranged to print papers of more than eight pages and up to sixteenpage papers, each page being half the regular size which the machine is designed to print.

The invention, in brief, is a novel combina tion of pasting mechanism, with a folder of the angle-bar or cow-catcher type.

lVith the old style of tape and tucker-bar folders it is an easy matter to paste a sixteenpage paper, as the paste can be applied after the web is severed into sheets and partly in the direction in which the webs are running; but with an angle-bar folder the paste must be applied transversely of the web before it is severed, and it is necessary to apply the paste at two different points and at different times'first, one application must be made on one web before it has passed the former, and the second application must be made after the webs have passed the former and been thereby folded to page widths, and, further, this second application of paste must be made to the partly-folded webs between the folds thereof and transverse to the direction in which they are running. On account of these difficulties in applying the paste it has heretofore been impossible to print and paste a sixteen-page paper on a Cox duplex press with angle-bar folder. By my present invention these difficulties are overcome and I am enabled to employ a cow-catcher or angle-bar folder and yet completely paste the papers by the employment of two pasting mechanisms, one of which applies the paste transversely to one of the webs (oronehave left the former the folds thereof are separated and one division is led past the second pasting mechanism, by which the paste is applied to the separated -fold transversely of the run thereof, and then the separated folds are reunited and passed through the cutting mechanism, by which the webs 6 5 are finally severed into sheet lengths, as newspapers, &c. Another advantage obtained by the present invention is that the slitting of the webs at the point of the former results in the upper edges of the sheets of the complete paper being entirely out or sep arated, thus leaving all pages properly free and open, while yet securely pasted at the back'margin.

The accompanying drawings illustrate a practical form of apparatus embodying the invention, showing an angle-bar folding and pasting mechanism for. a sixteen-page paper, particularly adapted to the improved Cox duplex press, but of course applicable to other printing-machines.

In said drawings, Figure 1 is a vertical lon gitudinal section through thefoldingand pasting mechanisms of the machine, and Fig. 2 is a transverse vertical sectional elevation of the 8 same. I

In said drawings, B designates the former of an angle-bar or cow-catcher folder, below which is a pair of coactin g rolls E E, by which the web is drawn over the former, and to. one 7 side thereof is a pair of cutting-cylinders I I, parallel with the rolls E E and through which the webs are finally led and by which they are severed into sheet lengths. These parts are of ordinary construction and need 5 no other specific explanation herein.

The invention may be employed in machines wherein two separate webs are printed and assembled at the folder, or it can be employed in machines wherein one extra-wide web is printed, which is thereafter split longitudinally before it reaches the former, one

half of such web being carried over anglebars and superimposed over the other half before reaching the former. Then the assembled halves of the doubled web are slit by the slitters in the former, as hereinafter described. For convenience'in explanation I refer to two webs, meaning thereby either origin ally-separate webs or the longitudinally opposite and separate halves of an originallysingle wide web.

At the top of the former is a pair of webguide rollers O and D, arranged one slightly above the other, and one-web W is led from the printing mechanism (not shown) over the roller D and down over the former to and between rolls E E, and another web to is led from the printing mechanism (not shown) to and under a guide 0, up to and over the roller O, and thence down over the former to the rolls E E, as shown, the webs IV and w meeting each other at the top of the former and passing down over the latter, being folded together longitudinally by the former and rolls E E in the usual manner. Prior to passing between the rolls E E, however, the webs are slitted longitudinally by a suitable mechanism located near the point of the former. As shown, this slitting mechanism consists of a pair of shear-acting cutter-disks M and M, disk M being mounted upon a shaft M behind the point of the former and disk M upon a shaft M above or exterior to the point of the former, which is slotted, as shown at b, to permit coaction of these disks. Shaft M may be driven by gears M and M from a shaft M suitably journaled in a bracketattached to the former, and shaft M may be driven by a sprocket M and chain M from a sprocket M on a shaft M driven by gears M and M from a gear M on the driving or power shaft F, as shown. The shaft M of disk M preferably has both a rotary and a longitudinal movement in its bearing in bracket M and may be. driven by a sprocket M and chain M from another sprocket M on said shaft M, as indicated in the drawings. A spring N is interposed between a shoulder on bracket M and a collar or washer N on shaft M between the hub of disk M and bracket M This spring keeps the disk M always laterally in contact with the disk M, so that these disks will shear-cut the web. The folds of the slitted webs after passing between rolls E are divided, half of both webs W and to being led down under a rollers K and thence directly up to and between the cutting-cylinders I I, and the other halves of Webs W and to being led over guiderollerz K K back to roller K, where they are reassembled with the other portions of the Webs W to and led therewith through the cutting-cylinders I I. The object of thus separating the folds of the webs is to enable the second pasting operation to be advantageously performed.

I shall now describe the'pasting mechanisms.

The first pasting mechanism is located between rolls 0 and O and is adapted to apply paste to the face of web w, transversely thereof. As shown, a wing-paster His employed, the wing being mounted on a shaft G which may be rotated by a train of gears G from a gear Gr on shaft F, as indicated in the drawings. The paster H receives paste from a roller G which rotates against the periphery of a roller G in the paste-pot G, as shown. The guide-roller 0 may be driven by or from one of the intermediate gears G, as indicated in the drawings. The second pasting mechanism is located in the loop formedin the separated folds of the split webs between the rolls E E and K and is adapted to apply the paste transversely to the folds, as indicated. As shown, the second paster is also a wingpaster H and is mounted on a shaft 16, located intermediate the guide-rollers K and K so as to be inclosed within the loop of the web between the roll E and roller K. Paster H is supplied with paste by a roll J from the pot J, as shown in Fig. 2. The shaft 16 may be provided with a large gear 15 and driven by a train of intermediate gears 14 from a gear on the shaft of the cutting-cylinder I, and the guide-rollers K K may be driven from gear 15 by intermediates 17, as shown. The shaft of the cutting-cylinder I may be driven by bevel-gears 12 13 from shaft F, as shown. The rolls E E are provided with intermeshing gears and may be driven from or by one of theintermediates 14:. Thearrangements of gearing for driving the several parts may be varied to suit the constructor, it only being necessary that the parts shall be driven at the desired relative speeds and in proper relative time.

Operation: The webs W w coming from the printing mechanisms are assembled as they. pass over the former B; but before they come together the paster H applies a line of paste to the margins of web W and transversely of the web, so that as these webs come down over the former they are pasted together transversely. The webs thus pasted together are slitted longitudinally as they pass the former and before they enter between the rolls E E, through which at least four thicknesses of paper pass. After passing between these rolls the folds of the slitted andpasted webs are separated, those folds of the web which passed over the left-hand edge of the former being led directly under roll K and thence to the cutting-cylinders, while those folds of the web which passed over the right-hand edge of the former are led up over roller K, down under roller K then back to the roller K, and then to the cutting-cylinders, the latter folds being thus looped around the second pasting mechanism, by which a second line of paste is applied transversely to the separated portion of the web at the point L, intermediate the rollers K and K. The separated folds of the webs are again reunited at roller K prior to passing between the cutting-cylin- ICC ders, so that the final pasting operation is completed before the Webs reach the cuttingcylinders. Thus the four thicknesses of the Webs will be securely and properly pasted together, and as they pass through the cuttingcylinders the webs are severed into sheet lengths, the sheets being all pasted together, however, so that the machine will deliver sixteen-page newspapers, for example, all properly pasted and folded. Thus by the present invention I am enabled to apply the paste to the web transversely thereof and transversely to the line of movement thereof both before and after the webs pass the former, thus enabling me to employ an angle-bar or cowcatcher folder, and by slitting the web, as described, I obtain the further advantage of freeing all the sheets, so that no subsequent cutting or trimming of the papers will be necessary to free the top edges of the sheets.

Practically one of the rolls K K K (preferably one of the latter) may be made laterally adjustable, so that the proper register of the margins can be maintained when the separatedfolds of the web are again reunited after the second pasting operation.

The feature of splitting webs longitudinally, separating the split port-ions, applying paste thereto while separated, and subsequently reuniting such portions and cutting them into sheet lengths might be usefully employed in connection with single webs.

That the practical applications of the in vention are numerous will be readily comprebended by those skilled in the ,art, and for the essential features and combinations thereof, for which protection is desired, reference is had to the following claims.
